You can clearly see that they have started to develop 'nubbins' and are no longer just kidney bean shaped. We suspect these 'nubbins' are probably the gills as they don't grow legs or arms until after they've hatched.

The Gills get bigger and colours get more defined - It looks like we have a wild-type (olive brown coloured) and the majority are Albino. Won't know until they are bigger if there are any golden type albinos or not... hopefully we'll have a good mix
